Description :
For the assessment of effect of thermal power plant effluents on the skeletal muscle of fish Catla catla,
histological, histochemical and biochemical methods were used and results were compared with control fish.
Histologically thermal power plant effluent exposed fish muscles showed marked thickening and separation of muscle
bundles, haemolysis, necrosis, lesions with reduced compactness was observed. Pronounced intramuscular oedema with
minor dystrophic changes and splitting muscles were also observed in the muscles of fish Catla catla exposed to the
thermal power plant effluents. The pathological findings included mild lymphocyte infiltration, vacuolar degeneration in
muscle bundles and atrophy of muscle bundles. Degeneration in muscle bundles with aggregations of inflammatory cells
between them and focal areas of necrosis were noticed. Vacuolar degeneration in muscle bundles and atrophy are also
observed in the muscle bundles might be due to the various concentrations of mixture of heavy metals in the thermal
power plant effluent. The physiological disturbances and morphological damages in the muscle tissue of fish caused due
to thermal power plant effluents pollutants. Histochemically the content of protein and carbohydrate in muscles tissue
was found to be decreased with decreased intensity of reaction in thermal power plant effluent exposed to fish as
compared to control. Biochemically In the fish exposed to the thermal power plant effluent showed increase in the content
of skeletal muscle protein and it was found to be 1.40 mg/gm.
